10513942 divided by 30 
We want to divide 10513942 by 30.

Moving on to step 1:
When dividing 1 by 30, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 30

Moving on to step 2:
10 divided by 30 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 10 after subtracting 0 from 10.
Include the next digit (5) from the dividend after 10, then repeat: 105 / 30

Advancing to step 3:
30 can be fit into 105 3 times, resulting in a remainder of 15.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 90 from 105 leaves us with 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 30

Let's proceed to step 4:
30 can be fit into 151 5 times, resulting in a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
If we take 150 away from 151, we end up with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 30

Advancing to step 5:
13 divided by 30 is 0 with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 350.0
Subtract 0 from 13 to get 13.
Grab the next digit (9) from the dividend, add it to 13, then carry on: 139 / 30

Going ahead to step 6:
30 goes into 139 4 times with a remainder of 19.
Put 4 as the next digit of the answer. 
Result so far: 3504.0
If we subtract 120 from 139, we get 19.
Append the next digit (4) from the dividend to 19 and continue with: 194 / 30

Advancing to step 7:
When dividing 194 by 30, we get 6 with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 35046.0
If we take 180 away from 194, we end up with 14.
Bring next digit (2) of the dividend behind the 14 and repeat the process: 142 / 30

Going ahead to step 8:
If we divide 142 by 30, we get 4 and a remainder of 22.
The next digit of our result is 4. 
Result so far: 350464.0
Subtract 120 from 142 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 9:
When dividing 220 by 30, we get 7 with a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 350464.7
Subtracting 210 from 220 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
If we divide 100 by 30, we get 3 and a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 350464.73
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 11:
The number 30 fits into 100 3 times, leaving a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 350464.733
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 350464.733 and a remainder of 0.001.
